BEIJING, March 25. /TASS/. US State Secretary John Kerry has lately become "a frequent guest" to Moscow, Kremlin Chief of Staff Sergey Ivanov said on Friday.

"Kerry has lately become a frequent guest to Moscow," Ivanov told journalists. "This is probably connected with something," he added.

Ivanov noted that he has not yet managed to familiarize himself with the results of Kerry’s visit to Moscow because the Kremlin chief of staff was on a two-day visit to Beijing. Ivanov thus could not comment on the results of US state secretary’s visit to Russia.
